IMPROVEMENT IN COFFlN-SCREWIS.

Specification forming part of Letters Patent No. 167,578, dated September 7, 1875; application filed August 16, 1875.

To all whom it may concern:

Be it known that I, WILLIAM M. SMITH, of West Meriden, in the county of New Haven and State of Connecticut, have invented a new Improvement in Collin-Screws; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent in- Figui'e l a side View 5 Fig. 2, a'vertical central section.

This invention relates to an improvement` in the article known to the trade as cofnscrews-that is to say, screws with an ornamental head, used for securing the top or 0rnamenting coins, the object being to. construct an elaborate head with a small quantity ot metal; and it consists in acap recessed upon its under side, and with the screw secured centrally therein, combined with a body through which the screw passes, and which sets into the recess in the cap, so that the projecting or overhanging edge of the cap forms a prominent part of the ornamentation.

Ais the cap, which is cast from the metal usually employed for such work, and with the head ot the screw B secured centrally therein upon the under side, preferably in the process of casting the cap. The cap is formed with a recess upon its under side, so as to make an overhanging edge, C. D is the body, which may be of any desirable form, perforated centrally, so that the screw may pass freely through it, and so as to set into the recess upon the under side of the cap, within the rim C, as shown.

This body maybe made from wood, and thus be very light and cheap. The rim of the cap hides the joint between the two parts, so that the appearance of the whole is as a solid or single-piece head.

The rim or overhanging edge of the cap may be ornamented to add materially to the appearance of the article.

I claim- The herein-described coffin-screw, consisting of the cap A, constructed witha recess upon its under side to produce an overhanging edge, and with a screw, B,attached thereto, combined with a separate body, I), inclosed by the rim of the cap, substantially as described.

WILLIAM SMITH.
